Booting from GRUB into Chimera

I set up a Hackintosh recently with software from tonymacx86. It’s great, super fast and cheap to boot! I also installed Ubuntu Linux 12.04 afterwards, and found that Linux’s GRUB bootloader took over the boot process, preventing me from loading Chameleon Chimera to boot into OSX. Here’s how I added an additional menu item to my grub.cfg to boot from GRUB into Chameleon.
